Childhood immunizations are vaccines given to children to protect them from various infectious diseases. These vaccines help the immune system recognize and fight off specific germs, reducing the risk of serious illnesses like measles, mumps, and whooping cough. Immunizations are typically administered during regular check-ups and follow a recommended schedule. Vaccines are safe and effective, and they not only protect the vaccinated child but also help prevent the spread of diseases in the community. By achieving high vaccination rates, communities can reach herd immunity, which protects those who cannot be vaccinated, such as infants and individuals with certain health conditions.
